Address Space Layout Randomisation (ASLR)

The term ‘address space layout randomisation’ (abbrev. ASLR) relates to a process of memory protection that operating system’s use to avoid the threat of attacks on buffer overflow. It does this by constantly changing the location of where executable files are loaded into the memory.

The reason this method is so successful against cyber attacks is that the attacker relies on knowing or being able to accurately estimate the location of certain functions and processes in computer memory. If an individual guesses the location wrongly, the system becomes alerted and the hacker’s application is closed and the attack is stopped in its tracks.

How much memory will my server need?

The amount of memory that your server requires depends on a number of different factors. Firstly you need to understand a few important things so you can make an informed decision.

The role of the server

The purpose of the server is to support shared applications and resources and deploy these to individual computers using a network. Servers can be responsible for a wide range of different things including email, databases, websites, files, applications, remote access terminal services, collaboration and audiovisual content. Each of these tasks will demand specific data processing and storage requirements which will have a significant impact on the amount of memory that the drive space will require for the best performance. File servers are less resource intensive than video or audio resources for example because they demand less memory and a reduced amount of space.

Servers can never have too much ram memory or space for storage but often space and cost implications often place restrictions on how much memory you can have. The best option is to select the most suitable amount of ram that can be used so that your programs run easily and the system is fully operational.

Users

Within your business, you will need to understand how many people will be accessing your server and what kind of tasks they carry out on a day to day basis. The more users that you have and the more tasks carried out the more memory that you will need. Servers which regularly exceed the available memory will see that the performance of the system will suffer considerably, slowing down or even halting the system completely. The amount of memory on a server will depend on the number of users that it can comfortably support and the number of applications that users can access simultaneously. Many business owners will assess the amount of storage that they need by assessing the amount of traffic based on the number of users or employees.

Demands on the Server

Demand is one of the main factors which will determine how much storage and ram memory you will require. The work that your employees will be carrying out is a fundamental consideration when you are assessing the level of memory that you need. Some businesses require more memory than others because their daily tasks are much more resource intensive. As an example, software developers or graphic designers will demand more storage space than a workforce who have to carry out routine administrative duties, working with word processing documents.

The more ram that a server has, the more efficient it will become and the speed at which employees or users can access information will be increased.

A server has a number of different functions and it can serve a variety of users so there are really no set guidelines on choosing the amount of memory that you will need. The more resource intensive the task, the higher number of users that you have will result in additional memory requirements so a good starting point is to determine who will be accessing the server and what they will be using it for.
